This paper presents the rationale for a novel approach to providing expressive, teachable, maintainable, and cost-effective special-purpose languages: A Semantically Enhanced Library Language (a SEL language or a SELL) is a dialect created by supersetting a language using a library and then subsetting the result using a tool that “understands” the syntax and semantics of both the underlying lan...

We describe a general method of detecting valid chains or links of pieces on a two-dimensional grid. Specifically, using the example of the chess variant known as Switch-Side Chain-Chess (SSCC). Presently, no foolproof method of detecting such chains in any given chess position is known and existing graph theory, to our knowledge, is unable to fully address this problem either. We therefore pro...

In order to speed-up the Navier-Stokes solver DROPS, which is developed at the IGPM (Institut für Geometrie und Praktische Mathematik) at the RWTH Aachen University, the most compute intense parts have been tuned and parallelized using OpenMP. The combination of the employed template programming techniques of the C++ programming language and the OpenMP parallelization approach caused problems w...

In this paper, a required introductory programming course being taught to MIS undergraduates using the C++ programming language is described. Two factors make the objectives of the course—which are to provide students with an exposure to the logical organization of the computer in addition to teaching them basic programming logic—particularly challenging to achieve. First, students enter the co...

Applied research in graph algorithms and combinatorial structures needs comprehensive and versatile software libraries. However, the design and the implementation of flexible libraries are challenging activities. Among the other problems involved in such a difficult field, a very special role is played by graph classification issues. We propose new techniques devised to help the designer and th...

Object-oriented programming using C++ classes is established practice in the general programming community and is beginning in computer music applications (Chaudhary, Freed et al. 1988; Chaudhary 1998). However, large components of computer music systems are still commonly written in the C programming language, either because object-orientation is felt unnecessary or more often because of effic...

This article documents the free computer algebra system “gTybalt”. The program is build on top of other packages, among others GiNaC, TeXmacs and Root. It offers the possibility of interactive symbolic calculations within the C++ programming language. Mathematical formulae are visualized using TeX fonts.

IPHC-PHENO-12-06 We present MadAnalysis 5, a new framework for phenomenological investigations at particle colliders. Based on a C++ kernel, this program allows us to efficiently perform, in a straightforward and user-friendly fashion, sophisticated physics analyses of event files such as those generated by a large class of Monte Carlo event generators. MadAnalysis 5 comes with two modes of run...

This paper describes the design, implementation and evaluation of an interactive virtual human Dr. Chestr: Computerized Host Encouraging Students to Review. Game show hosts exert a unique personality that becomes the trademark of their respective game shows. Our aim is to create virtual humans that can interact naturally and spontaneously using speech, emotions and gesture. Dr. Chestr is our vi...
